PATENTYQFFFICE 1 MARVIN B. SMITH, or srnnona, wEsr VIRGINIA BURNER Application filed May 12, 1930. serial to. 451,817. r

This invention relates to improvements in a burner which forms the subject matter of a patent granted to me on July 8, 1913, No. 1,067,069, the general object of the present invention being to provide means for increasing the efficiency of the said burner by providing means for preventing back firing and also means for regulating the flow of gasinto the gas chamber.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a front view of the improved burner, with parts broken away.

Figure 2 is a top plan view.

Figure 3 is an end view.

Figure 4 is a section on ure 1.

In these views, the numeral 1 indicates the supporting member and the numeral 2 indicates the channel shaped members which are connected with the supporting member and form the gas chambers. These members are corrugated at their upper ends, as shown at 3, which prevents the gas from back firing. The gas supply pipe is shown at 4:, and is supported on the member 1 by the brackets 5 in such a manner that the pipe has rotary movement. The pipe is provided with the ports 6, one of which is located under the lower end of each chamber so that gas can pass from the pipe into the chamber.

A rod 7 is rotatably supported by the brackets 5 above the pipe 4 and tongues 8 are .fastened to the red, one of these tongues being arranged in each chamber and said tongues act to regulate the flow of gas into the gas chambers. The rod can be adjusted to adjust the tongues through means of a nut 9 on a threaded stem 10 fastened to the base and having an annular groove therein to receive line 44: of Figthe forked end of an arm 11 fastened to one end of the shaft. Thus by turning the screw, the shaft or rod 7 is partly turned so as to adjust the tongues in the chambers which, as before stated, control or regulate the flow of gas into the chambers.

An arm 12 is fastened to the pipe 4 and carries a set screw 13 which moves overa bracket 14; on the supporting member. Thus the pipe can be partly rotated to adjust the position of the ports 6 in relation to the lower ends of the gas chambers by moving the arm and then looking it in adjusted position by the set screw. This arrangement permits the gas to enter the chambers at any desired point.

From the foregoing it will-be seen that I have provided means for adjusting the point of entrance of the gas in the chambers, adjustable tongues for regulating the flow of gas into the gas chambers and corrugations at the upper ends of the chambers for preventing back fire.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is 1. A. burner of the class described comd the supporting member a gas chamber, a pipe gs arranged under the chamber and having a port therein for directing gas into the lower end of the chamber, a rod located below the chamber, a tongue on the rod extending into the lower part of the chamber and means for adjusting the rod to adjust the position of the tongue in the chamber.

3. A burner of the class described comprising a supporting member, a channel shaped member fastened thereto and forming with the supporting member a gas chamber, a supply pipe rotatably connected with the supporting member under the chamber and having a port therein for directing gas into the lower end of the chamber and means for partially rotating the pipe whereby the gas from the port can enter any desired part of the lower end of the chamber.

In testimony whereof I a'lfix my signature.

MARVIN 'B. SMITH
